Abstract

We isolated ten trains of parasitic mealybug damaging the root of black pepper. One of the strains is highly pathogenic to both nymphs and adults of root mealybug. In the laboratory, the strain’s effectiveness against black pepper root mealybugs is different, depending on conidial concentrations. At 1 × 108 and 1 × 109 conidia/mL concentrations, the effectiveness is 946.7 and 996.3 in the nymph stage and 951.9 and 1001.9 in the adult stage. At 1 × 107, 1 × 106 and 1 × 105 conidia/mL concentrations, the effectiveness is below 793 in the stages.
